cytoplasmic inheritance  mitochondrial i.

dominant inheritance  see under gene.

extrachromosomal inheritance  mitochondrial i.

intermediate inheritance  inheritance in which the phenotype of the heterozygote falls between that of either homozygote.

maternal inheritance  mitochondrial i.

mitochondrial inheritance  the inheritance of traits controlled by genes on the DNA of mitochondria in the ooplasm; thus the genes are inherited entirely from the maternal side, segregate randomly at meiosis or mitosis, and are variably expressed.

recessive inheritance  see under gene.

sex-linked inheritance  see under gene.

cytoplasmic inheritance

[sī′tōplaz′mik]

the acquisition of traits or conditions controlled by self-replicating substances within the cytoplasm, such as mitochondria or chloroplasts, rather than by genes on the chromosomes in the nucleus. The phenomenon occurs in plants and some animals but has not been demonstrated in humans.

cytoplasmic

pertaining to or included in cytoplasm.

cytoplasmic inclusions

include secretory inclusions (enzymes, acids, proteins, mucosubstances), nutritive inclusions (glycogen, lipids), pigment granules (melanin, lipofuscin, hemosiderin). See also inclusion body.

cytoplasmic inheritance

the cytoplasmic organelles, chloroplasts and mitochondria contain DNA which contains a number of genes. These extrachromosomal genes are transmitted to daughter cells via cytoplasm. Called also maternal inheritance.

cytoplasmic nuclear inclusion

see inclusion body.

cytoplasmic skeleton

includes microtubules, centrioles, cilia, flagellae.
